Hello All: After our wonderful Zoom tonight "Just Landed", I promised to put you in touch with my real estate agent here locally in Porto. He does both rentals and sales. I have met several of his satisfied clients.
His name is Daniel Ramos with Coldwell Banker reach him at +351 971 640 661 via phone, text or WhatsApp.
After I found my apartment he took me to get my phone/internet/Television, helped with utilities, took me and Charlie, my Chi-weenie to the vet to get our pet passport and helped me with my Portuguese health insurance. All of this and no additional payments which I found are common amongst the local agents. "Buyers agents" here claim you have to pay them directly, but they get paid by splitting the commission with the seller/landlord agents.
Agents here are not licensed, only brokers are required to take a test and get a license.
Feel free to contact me here for any help I can give. (Which isn't much! LOL)
You will find that expats are willing to help because someone helped them.
Also, reach out to your Portuguese neighbors at pubs, in parks and on the street. They are so warm and helpful and you might make a new friend.
